IKEA (瑞典宜家家具公司) is set to launch (上市) an air-purifying curtain coated with a mineral-based surface that breaks down common pollutants. The surface of the curtain is treated with a photocatalyst (光催化剂) mineral that causes air pollution to break down when light shines through it, allowing users to purify the air in their own homes.
The technology works in a similar way to photosynthesis - the natural process that plants and some other organisms use to change carbon dioxide and water into food, using light.
Developed over several years by IKEA in collaboration with universities across Europe and Asia, the purifying technology works with both natural and artificial light. “For me, it’s important to work on products that solve actual problems and are relevant to people,” explained IKEA product developer Mauricio Affonso. “We are creating an affordable and space-saving air purifying solution that also makes the home more beautiful,” he continued.
The World Health Organisation (WHO) has stated that even now, 91 percent of the world's population live in areas where air pollution goes over WHO guideline limits. The effects of poor air kill about seven million people worldwide each year, research by the WHO has found.
“Besides enabling people to breathe better air at home, we hope that the curtain will increase people's awareness of indoor air pollution, inspiring behavioral changes that contribute to a world of clean air,” said IKEA head of sustainability Lena Pripp-Kovac. “It is the first product to use the technology, but the development will give us opportunities for future applications on other textiles (纺织品).”
“We know that there is no single solution to air pollution. We work long term for positive change, to enable people to live healthier lives,” added Pripp-Kovac.

They have beaten us at chess, and now computers are taking a step into a very human territory: the reading comprehension test.
Alibaba said its artificial research outperformed human beings in a global reading comprehension test that seeks answers to such pressing questions as “what was Nikola Tesla’s ethnicity (种族划分)?” and “how big is the Amazon rainforest?”
Luo Si described the machines’ victory as “a milestone”. He said the technology has many uses, from customer service to museum tutorial (教程) to medical inquires — some of which are already being handled by chatbots globally.
In the test, companies subjected their artificial intelligence systems to questions from the Stanford Question Answering Dataset, which assessed reading comprehension. The computers’ answers were compared against average human responses and ranked.
Tying (打平) in top place were Microsoft, the US software giant, and Alibaba, and — like its peers at home and abroad - is putting more funds into AI, much of it via its research arm.
While Microsoft and Alibaba won by the slimmest of margins (幅度) — at accuracy levels a few basis points (基点) above humans’ 82.3 per cent in providing exact matches to questions- the tie provided a symbol of the AI arms race (军备竞赛) launched by the US and China.
China aims to use its vast data, collected from its 1.4 billion population including 730 million who are online, and financial resources to overtake the US in creating a $150 billion industry that is seen as the next industrial revolution.
Baidu made an early bet on AI, and is leading its rivals in autonomous driving. Tencent, which boasts 1 billion monthly active users on its social media WeChat app, and Alibaba have adopted AI in operations such as customizing news and ads, and are investing in new fields.
1.What does Luo Si think of AI’s performance in reading comprehension?
A.He feels frightened at it. B.He has some doubts about it.
C.He thinks highly of it. D.He considers it worth a try.
2.What does China depend on to lead in AI?
A.The new industrial revolution.
B.The huge market of $150 billion industry investment.
C.The vast amount of data from its 1.4 billion population.
D.The cooperation between Chinese government and Microsoft.
3.In which field does Baidu do better than its rivals?
A.The medical enquiries. B.The customer service.
C.Customer news feeds. D.The driverless cars.
I've enjoyed countless gatherings of Thanksgiving, from traditional family gatherings to feasts with many new faces. Yet at age 65, I have never spent the holiday with a husband or children of my own.
If you feel pity for me, please don’t — I am proud of the decision I made decades ago to change from life’s conventional road map, and I have no regrets about it. I enjoy being alone.
I found my life deeply rewarding. At the same time, I was fascinated with the question of why my adult life as a single person was not as valued by the people around me or by society. When people learned I was single with no children, they assumed my life had a hole that needed filling.
I wondered: Was it just me, or were other single people viewed the same way? I teamed up with my colleague, Wendy Morris, and she and I began a series of studies investigating how people characterize single and married people. The research shows that single people typically have more friends than married people do. They also do more to help, support, and stay in touch with their parents, friends, and neighbors.
I’ve lived my life in cheerful, unapologetic refusal of the “get married, have kids” road map. But getting married is deeply ingrained in our society, and it can be difficult to break completely free of the marriage-plus-children ideal.
The research and the books, though, are not enough. We all need to think about life more open-mindedly. Instead of asking whether you do or don't want to marry or have kids, ask: What will make your life meaningful and fulfilling? When you think about it that way, the possibilities are limitless.

My friend Lilly and I were on the way back to home from school when we saw a boy fall off his bicycles. The boy lay on the ground， screamed in pain. We rushed to help and found if the boy's left leg was bleeding. It happened that we have learned some knowledge about first aid before， so we knew how we should do. We dialed "120" and called an ambulance. While waiting it， I took out my handkerchief and pressed them onto the bleeding point. Then we rolled the boy onto one side but put him in the recovery position. We stayed with him until the ambulance arrived 5 minutes late.
